Solve the equation. –18 = p over 2

1 answer:

dimulka [17.4K]4 years ago

Answer:

Step-by-step explanation:

-18 = p / 2....multiply both sides by 2, cancelling out the 2 on the right side

-18 * 2 = p

- 36 = p <===

if it makes it easier to understand, p/2 is the same as (1/2)p

What is the inverse of function f? F(X) = square root of x +7

katrin2010 [14]

Answer: $f^{-1} (x)=x^{2} -7$

Step-by-step explanation:

To find the inverse of a function replace f(x) with x and the original x with y

$f(x)=\sqrt{x+7} \\x=\sqrt{y+7}$

Now we can solve for y

Square both sides so we can cancel out the root

$x=\sqrt{y+7}\\x^{2} =\sqrt{y+7}^{2} \\x^{2} =y+7$

Now subtract 7 from both sides

$x^{2} =y+7\\x^{2} -7=y+7-7\\x^{2} -7=y$

Now replace y with the inverse of f(x), $f^{-1} (x)$

Limit question: lim x-->pi ((e^sinx)-1)/(x-pi)

aleksandr82 [10.1K]

$\displaystyle\lim_{x\to\pi}\dfrac{e^{\sin x}-1}{x-\pi}$

Notice that if $f(x)=e^{\sin x}$ , then $f(\pi)=e^{\sin\pi}=e^0=1$ . Recall the definition of the derivative of a function $f(x)$ at a point $x=c$ :

$f'(c):=\displaystyle\lim_{x\to c}\frac{f(x)-f(c)}{x-c}$

So the value of this limit is exactly the value of the derivative of $f(x)=e^{\sin x}$ at $x=\pi$ .

You have

$f'(x)=\cos x\,e^{\sin x}\implies f'(\pi)=\cos\pi\,e^{\sin\pi}=-1$

Geometry only answer if you know

nalin [4]

<h2><u>My complete work</u> :</h2>

Given :

∠F = ∠J
∠D = ∠H
∠E = ∠I

Sum of all angles in a triangle = 180°

Which means :

41 + 20 + 15x - 1 = 180

$= \tt61 + 15x - 1 = 180$

$=\tt 61 - 1 + 15x = 180$

$=\tt 60 + 15x = 180$

$= \tt15x = 180 - 60$

$=\tt 15x = 120$

$= \tt \: x = \frac{120}{15}$

$=\tt x = 18$

Thus, the value of x = 18

Measure of angle 15x-1 :

$= \tt15 \times 8 - 1$

$=\tt120 - 1$

$=\tt 119$

Thus, the measure of angle 15x-1 = 119°

Let us place 8 in the place of x to see if we have found out the correct measure of the angles :

$= \tt40 + 21 + 119 = 180$

$= \tt61 + 119 = 180$

$=\tt 180 = 180$

Since the measures of all the angle sum up to form 180°, we can conclude that we have found out the correct measure of each of the angles.

Therefore, the value of x = 8

$\boxed{\color{plum}\bold{x = 8}}$
